Q. Consider the following rivers:
  1. Narmada
  2. Mahi
  3. Luni
  4. Tawa
  5. Sharavathi
Which of the above are west flowing rivers that drain into the Arabian Sea?

Answer: Only 1, 2 and 5
Notes: Narmada, Mahi, and Sharavathi are west-flowing rivers draining into the Arabian Sea. Luni, although flowing west, is endorheic and does not reach the Arabian Sea. Tawa is a tributary of Narmada and does not independently reach the sea. Hence, only 1, 2, and 5 drain west into the Arabian Sea.
